| Summary: | Introduction: Lateral window sinus augmentation is done to
augment the vertical sinus height for implant placement. Putty
alloplasts have been used due to their longer resorption time
and provide resistance to implant insertion. Although, widely
used, the stability and bone loss around implants placed
simultaneously following sinus augmentation with putty bone
graft has not been evaluated.
Aim: To evaluate the effect of putty alloplastic bone substitute
on implant stability.
Materials and Methods: This prospective interventional study
was conducted in the Outpatient Department (OPD) of Oral
and Maxillofacial surgery at SGT Dental College and Research
Institute, Gurugram, Haryana, India. The duration of the study
was two years and 11 months, from December 2014-November
2016. A total of 15 implants were placed simultaneously after
lateral window sinus augmentation. Primary implant stability
measurements were done using Resonance Frequency Analysis
(RFA). Vertical Bone Height (VBH), Maximum Insertion Torque
(MIT) and Crestal Bone Loss (CBL) were measured till six months
of follow-up. The data was analysed using standard statistical
analyses with Shapiro-Wilk-test, Wilcoxon signed-rank test and
Spearman’s correlation co-efficient.
Results: The mean age of the study participants was 58±3.04
years. A total of 15 implants were placed in 12 patients.
Adequate primary stability was achieved with MIT >36 N/cm2
in
9/15 patients whereas, in 6/15 patients the MIT was ≤36 N/cm2
.
The implants showed 100% survival rate. Postoperative bone
gain obtained was in the range of 7.89 mm to 11.9 mm, with a
mean of 9.92 mm. Acceptable levels of implant stability were
obtained after six months.
Conclusion: Within the limitations of the study, it can be
concluded that, putty bone alloplast can serve as an adequate
bone substitute in simultaneous implant placement after lateral
window sinus augmentation and help in achieving stability. |
